At the beginning of the rainy season around the middle of May, in the Central and Southern of Laos, the Boun Bangfai or the rocket festival is held. The festival is a call for rain and a celebration of fertility. In the morning, a religious ceremony is performed. In the afternoon, people gather in the fields on the surrounding of towns to launch self-made firework rockets. Different communities compete for the best decorated and the highest traveling rocket. Men disguised as women perform vaudeville acts using wooden phalli in order to anger the gods. As revenge, the gods are expected to send thunderstorms. The rocket festivals are organized from place to place to enable greater participation and attendance.
